A convergent total synthesis of the tetrahydropyran-bearing acetogenin (+)-muconin 1 is described. All five chiral building blocks 7, 9, 17, 21, and 29 were prepared from d-glutamic acid, respectively. Four out of them were used to furnish the alkyne 16 and the iodoalkyne 33, respectively, and palladium(0)-mediated cross-coupling of alkynes 16 and 33, followed by hydrogenation, afforded 36. Simultaneous
描述了具有四氢吡喃的产乙酸原蛋白(+)-粘蛋白1的会聚全合成。所有五个手性构建块7,9,17,21,和29,从d谷氨酸分别制备。其中四个用于分别提供炔烃16和碘代炔烃33,以及钯(0)介导的炔烃16和33的交叉偶联,然后氢化,得到36。同时用BF 3 Et 2对36个MOM和TBS基团同时脱保护O在存在Me 2 S的情况下提供(+)-muconin 1。
